Now available from Bestech Australia is the Gladiator 'Landmark' 20GPS/AHRS eXT high quality and enhanced MEMS AHRS altitude heading reading system.
The new AHRS is a performance enhanced upgrade from the Gladiator standard Landmark® 20AHRS.
The new instrument has lower noise accelerometers with improved temperature bias performance as well as a ruggedized environmentally sealed packaging and a MIL spec connector.
The low noise accelerometers and gyros enable precision measurement and improved in-run and bias over temperature, as well as reduced jitter on the attitude indicator display. The performance of the AHRS is optimised with fully temperature compensated bias and scale factors and compensated misalignment g-sensitivity.
Applications for the new AHRS are in fixed and rotary wing aircraft, automotive and motor cycle testing, motor sports, commercial aircraft and marine craft and submarine device testing.
The ruggedized environmental packaging and overall design enables the new AHRS to be used where high performance is required. The new AHRS is ideal where dependability in hostile environments, and the altitude and heading measurements need to be made at relatively low cost.
The measured parameters of the Gladiator ‘LandMark’ 20GPS/AHRS eXT include heading, altitude, pitch, roll, yaw, pressure, altitude and temperature.
A set of gyro, accelerometer, and magnetometer is included for each axis (X,Y & Z). Other sensors include a pressure sensor and 6 temperature sensors. The output signals from each of the inertial sensors, the magnetometers, plus the pressure sensor and one temperature sensor, are transmitted via the RS485 port.
The physical size of the Landmark 20 GPS/AHRS eXT is 6.7 x 4.5 x 3.75cm (L x W x H) and it weighs 120 gram. Input voltage is +3.1 to 4.2V maximum. At 3.3V, the power drain is 473W (typical).
The MTBF is 31,400 hours in accordance with MIL –STD-217F. The shock rating is 500 g (1/2 sine, 30mSec powered), and the operating temperature is from -40 to +85°C.
Informed application and backup support for the Landmark 20 GPS/AHRS eXT is provided by Bestech Australia
which has many years experience in the supply and support for inertial measurement devices, including more complex devices including the new Gladiator ‘Landmark’ 20 GPS/AHRS eXT.
